TRAP FO'R REFRIGERATOR DRAIN-PIPES.

SPECIFICATION forming part of'Lette'rs Patent No. 646,606, dated April 3, 1900.

Application filed April 4,1898. :Serial lilo. 676,289. (No model.)

To all whom it tncty'wncern: 7

Be it known that 1, JAMES I. PAYNE, a citizen of the United States, and a' resident of Arlington Heights, in the county of Hamilton and State'of Ohio, have invented certain new and useful'lmprovements in Traps for R67 frigerator Drain-Pipes, of wh ich the following is a specification.

Among the various object-slot my-inveution there may here be noted, first simplicity of construction; secondly, economy of manufacture; thirdly, enlarged capacity of adapta tion, and, fourthly, easeof 1nanipulation'. The several features of my invention will be apparent from the following description and'claimsf a In the accompanying drawings, making part. of this specification, Figure 1 represents a frontv elevation of a refrigerator and ofithe devices of my invention applied thereto. 1 Fig. 2 is a View inperspective 'ofmy traploy itself. Fig. 3 is a vertical central section 'of'the trap;

taken in a plane at right angles to the axis of the pivot connecting the two portions of the trap.

certain featuresof my invention." I p \Vhile I have shownm'y invention applied to one style of v refrigerator in order to illustrate its functions and advantages, I wish to be understood that the trap isfapplicable to,

other descriptionsand kinds of refrigerators having a-drip-pipe.

I will now proceed todescribe my'inven tion.

A indicates a bowl, preferably of an invert-' ed conical form and provided at its upper edge with an outlying flange A The lower end or bottom of the bowl is-open and is extended in the shape of a pi pe A substantially asshown. Below this device A A A is suspended a bowl B, and the'axial center of the latter, if extended upward, passes to the side of the pipe'A 'Between the upper device A A and the lower bowl 13 there is a pivotal connection, and this connection is such that the bowl B is suspended in the line of its Vertical axial center by said pivotal connection. The preferred specific construction of this pivotal connection is as follows: From the upper bowl A projects a narrow flange A Figsand 5' are 'eachsectional views illustrating con'str ctionsj setting forth which extends part Way down along the pipe A and outwardly therefrom. This flange is preferably integral with the bowl A and pipe A I I Fro nthe central part of the upper side of thebottom of the-bowl B rises a pedestal or stud B and at its upper end terminates in I the lower portion of the flange A. There are holes B through these flanges B and there two flanges B 13 between which is received is a hole A through the flange'A A pivotrod passes through one of the holes B then through the hole Aiand then'through the- -other hole B Thus the bowl B is pivoted to the upper device. The preferred form of pivot is that known as a split key. The latter. will not work out when the bowl B is swung back. and forth on said pivot. the bowl B is securelyrpivoted to the device A A A The-pipe'A extends down into the bowlB at one side of the pivot-standard B [In practice my improved trap is applied and-used as follows: The flange A is secured against and to the bottomof'the refrigerator,

so that the lowerend of the drain-pipe O of the refrigerator shall duly ext-end down into the bowl A, the axial centerof the drain-pipe O being coincident with the axial center of the bowl and pipe A A substantially as shown in Fig. 3. The shape of the'device A A? A- is intentionally such as to enable the trap to be used overthat is, embracingv from below up+a number of different sizes of drain-pipe. For example,the device in the drawings,which is there shown'ona scale of about two-thirds Such a general con- Thus pivot A", applied as shown in the drawings. 7 This pivot is preferably a split key, as shown, as it is easily attached or removed, but'will keep itsplace as a pivot until removed by human agency. v In operation the water from the melting ice flows down through the drain pipe and through the device A A into the bowl B. The water fills the latter and therefore rises above the bottom of the pipe A and thus forms a water seal after the manner of atrap and prevents the air or gases within the ref rigerator from passing out through this trap, and vice versa prevents gases outside the refrigerator from entering the latter through this trap. The water in the bowl overflows the latter. A suitable receptacle is usually placed beneath the trap, and into this the water from the trap will fall. Any sediment coming down the drain-pipe with the water from the melting ice will be deposited in the bowl B, and when suflicient sedimenthas been collected therein it is cleaned. The removal of the sediment and cleansing of the bowl are readily effected by tipping the bowl. When the bowl is cleansed of sediment, the hold on the bowl is relinquished, and the latter willautomatically return to its normal position, as shown in Fig. 2. It will be understood that the bowl does not automatically upset, but requires to be upset by human agency. However, it will, whenever permitted, automatically return to its original and normal position.

It will be observed that this trap canreadily be applied to the refrigerator and that when once secured to the latter it cannot become detached from its connection with the drippipe. The trap is simple in construction and economical of manufacture and easily manipulated. Itis a trap that will always be a trap. It has also enlarged capacity for adaptation to drain-pipes of different diameters.

The bottom of the trap in any of its preferred modes of application to a refrigerator will not extend below the base-board of the refrigerator, and the floor is located so that when the trap is screwed to it the lowermost part of the trap will not extend below the base-board of the refrigerator. Hence any drip-receptacle that can be put under the baseboard will also go under the trap. This arrangement allows for the drip-receptacle of large capacity.

In Fig.4 I present a description of trap in which the feature of the centrally-suspended trap-bowl B and a drain-delivery conduit extends down into the space of this bowl. In this case the drain-delivery conduit is the drain-pipe O of the refrigerator. In this instance the bowl. is suspended from the hanger A connected to the base of the refrigerator. This latter device is not so desirable as the construction shown in Figs. 2 and 3, because the ordinary drain-pipes are made of zinc or galvanized iron and wear out and deteriorate 'quite rapidly at the ends. Hence this arrangement would be only temporary in its efficiency.

Instead of the construction shown in Fig. 4 the drain-pipe C may be provided with a projection A clamped or otherwise secured to this drain-pipe. In the figure is shown a ring-clamp A, having cars A. Through the latter a screw passes and draws the ears together. To this projection the bowl B may be axially suspended, as illustrated in Fig. 5.

The construction first described and Well illustrated in Figs. 2 and 3 is greatly preferable to the others specified, because (among other reasons) it protects the exposed sides of the end and the bottom edge of the drippipe with an eflicient guard made usually of cast-iron galvanized and lasting, so to speak, indefinitely.

WVhat I claim as new and of my invention, and desire to secure by Letters Patent, is-

1. In a refrigerator, the combination of a bowl A, and a hollow prolongation or pipe A from an opening in the bottom of the bowl, and a flange or projection A extending from the side of this upper portion of the trap, and a lower bowl having a stud centrally located in the latter and extending upward from the bottom of the latter, and pivotally connected to the projection A the pipe A extending down into the bowl, substantially as and for the purposes specified.

2. In a refrigerator, the combination of a bowl A, and a hollow prolongation or pipe A from an opening in the bottom of the bowl, and a flange or projection A extending from the side of this upper portion of the trap, and a lower bowl having a stud centrally located in the latter and extending upward from the bottom of the latter, and having a notch receiving the flange A, and there pivoted together, the pipe A extending down into the bowl, substantially as and for the purposes specified.
